New podand-type fluoroionophores having two pyrene moieties: 2,2´-bis(1-pyrenylacetyloxy)diphenyl sulfide (3), 2,2´-bis(1-pyrenylacetyloxy)diphenyl sulfoxide (4), and 2,2´-bis(1-pyrenylacetyloxy)diphenyl sulfone (5), have been synthesized by connecting two 1-pyrenecarbonylmethyl groups with the two hydroxy groups of 2,2´-dihydroxydiphenyl sulfide, sulfoxide, and sulfone, respectively. Their complexation behavior

A facile one-pot C-benzylation of various sodium enolates derived from methyl malonate, beta-ketoesters, a beta-cyanoester, a beta-cyanosulfone, ketones and a carboxylic ester is reported. Reaction of alkoxydiphenylsulfonium salts formed by treating various benzyl alcohols with diphenyl sulfide bis(trifluoromethanesulfonate) (derived from

Structure activity studies on [4-(phenylsulfonyl)phenyl]methylpiperazine led to the discovery of 4-cyclohexyl-alpha-[4-[[4-methoxyphenyl(S)-sufinyl]phenyl]-1-pi perazineacetonitrile, 1, an M2 selective muscarinic antagonist. Affinity at the cloned human M2 receptor was 2.7 nM; the M1/M2 selectivity is 40-fold.

To characterize the properties of diphenyl sulfoxide (DPSO) as a new type of electron acceptor for guinea pig liver aldehyde oxidase (AO), we compared the kinetics of the reductions of DPSO and other classical electron acceptors such as O2 and

Sulfoxides are frequently used in organic synthesis as chiral auxiliaries and reagents to mediate a wide variety of chemical transformations. For example, diphenyl sulfoxide and triflic anhydride can be used to activate a wide range of glycosyl donors including hemiacetals

To evaluate the metabolic capacity of intact guinea pig liver under normoxic and hypoxic conditions, oxidative and reductive metabolism of diphenyl sulfoxide (DPSO) was studied by the nonrecirculating perfusion method in situ. DPSO was exclusively converted into diphenyl sulfone (DPSO2)

1. Radiolabelled diphenyl sulphoxide (U-14C- or 35S-) was administered by gavage (1.0 mmol/kg body weight) to the adult male Wistar rat following an overnight fast. 2. For both labelled forms faeces was the major route of excretion of radioactivity (50%)

The reduction of sulindac, sulphinpyrazone and diphenyl sulphoxide to their thioether analogues has been studied in vitro using rat and rabbit tissues. Sulindac reduction was about 10-fold higher in homogenates of rat kidney and liver than in other tissues although

More than 50 years have passed since Haszeldine reported the first addition of a trifluoromethyl radical to an allene; in the intervening years, both the chemistry of allenes and the reactivity of single-electron species have become topics of intense interest.

Diphenylsulfoxide in combination with triflic anhydride provides a very potent thiophilic glycosylation promotor system, capable of activating disarmed thioglycosides. The usefulness of this novel thiophilic activator is illustrated in a successful chemoselective glycosylation sequence in which the donor thioglycoside in

An N-acetyl-5-N,4-O-oxazolidinone-protected p-toluene 2-thio-sialoside donor, promoted by Ph(2)SO/Tf(2)O/TTBPy, was thoroughly investigated in the coupling to various acceptors. The stereoselectivity of the sialylation was found to be dependent on the various reaction conditions, such as pre-activation time, reaction time, the amount

Radiolabelled [UL-14C]-diphenyl sulphide, [UL-14C]-diphenyl sulphoxide and [UL-14C]-diphenyl sulphone were administered by gavage (1.0 mmol/kg body weight) to adult male Wistar rats following an overnight fast. For all compounds, faeces were the major route of excretion of radioactivity (50%). Urinary elimination

The formation of sialic acid glycosides with a thiosialic acid derivative, diphenyl sulfoxide, and trifluoromethanesulfonic anhydride is reported. With an excess of diphenyl sulfoxide, glycal formation can be completely suppressed and excellent yields are obtained for coupling to a wide

An efficient approach to the dehydrative sialylation of various substrates with C-4-aminated sialyl-hemiketal donors by using the reagent combination of diphenyl sulfoxide and triflic anhydride is reported. By using a C-4-hindered non-nucleophilic amine auxiliary, excellent yields and high alpha-stereoselectivities were

The caecal microflora from female rats show a greater ability to reduce the sulphoxide group of sulindac than either the liver or kidneys. Studies on sulphoxide reduction by Escherichia coli showed that NADH, NADPH and dithiothreitol (DTT), but not acetaldehyde
